MACHINE FOR MARKING SHINGLES.

SPECIFICATION forming part of Letters Patent No. 235,095, dated December'7, 1880.

Application filed May 26, 1880.

To all whom it may concern: I

Be it known that I, MARsHALL MOGOMB, of Pittsburg, Allegheny county,Pennsylvania, have invented an Improvement in Machines for MarkingShingles, of which the following is a specification.

My invention relates to the manufacture of that class of shinglesprovided with one or more marks or lines upon the faces or edges, forthe purpose of determining the position of the overlying course ofshingles without the necessity of making the usual coursing-lines; andmy invention. consists of an apparatus, constructed as hereinafterdescribed, to rapidly and accurately mark the shingles.

In the drawings forming part of this specification, Figure l is aperspective view of a shingle marked with coursing-lines. Fig. 2 is aside elevation of an apparatus which I employ in marking the shingles.Fig. 3 is a plan view; Fig. 4, an end elevation; Fig. 5, a side Viewlooking in the direction of the arrow, Fig. 3 and Fig. 6, amodification.

The essential features of the apparatus are a bed or way upon which theshingles travel, a marking device. and a gage, whereby the relativeposition of the shingles to the markin g device is maintained. Thesefeatures may be constructed in various ways. For instance, the bed mayconsist of a traveling belt carrying the shingles, or of a flat,horizontal, or inclined table, over which the shingles are passed, byhand or gravity, beneath the marking dev1ce.

The gage is a rib or bearing against which the butts or ends of theshingles bear, so as to insure the mark on all the shingles at a uniformdistance from the ends.

In Figs. 2 to 5 the way consists of an endless belt, A, carried uponrollers B B, at opposite ends ot the base-plate O, at the rear of whicha standard, D, constitutes the gage or hearing for the ends of theshingle.

An overhanging arm, E, extending from the front side of the standard D,supports the marking device in its proper position above the belt A,this device, in the present instance,

(No model.)

consisting of a roller, G, provided with annular printing-ribs a, whichare inked by a train of rollers, b 1) b fed from a fountain, H.

The upper roller, N, is moved intermittently from an eccentric, c, onthe driving-shaft I, which eccentric reciprocates a rod, d, the end ofwhich engages with a ratchet, e, on the shaft of the roller b The rollerb is mounted on the shaft I, and bears upon the ribs a of the roller G,and also drives frictionally the roller I), mounted eccentrically uponits shaft, so as to touch the roller 1) but once and for a short time inthe course of each revolution. A lateral motion is also given to theroller 1), which may be imparted by a pin, 1', extending into acam-groove, f, in the shaft of the roller.

The shaft I is driven from any suitable source of power, as are also therollers B B, and the shingles are placedsuccessively upon the travelingbelt or way, and are carried by the latter beneath the roller G and incontact with,

its marking-ribs, by means of which two clear, well-defined lines,parallel to the end, are printed upon each shingle, the operation beingperformed as rapidly as the shingles can be carried beneath the markingdevice.

By this means the shingles are marked so rapidly and cheaply that theymay be sold with profit at acost of but a few cents per thousand inexcess of the price of the unmarked shingles.

While the shingles might be pushed along the base 0 as a way, the beltis much preferable, as it will yield so as to insure the contact of theshingles with the printing device whatever may be their thickness,securing a positive mark in all cases and avoiding undue pressure uponthe printing device.

By altering the relative position of the marker and gage D the point atwhich the line is made may be determined, as desired. For this purpose amarking device, F, may be secured adjustably to the bracket E by a boltand nut, J, as shown, or the marking device may be suspendedpermanently, and the gage D made adjustable.

It will be evident that the marking device may be used beneath the way,so as to mark the shingles passing over the said device.

In some instances feed-rolls 0r feed-wheels K may be secured to theshaft I, to facilitate and insure the accurate movement of the shingles.

In place of the printing-roll and train described, the marking devicemaybe a circular reservoir filled with ink, which passes to a peripheralwick, as shown in Fi 6, or it may be a plumbago disk clamped between twoplates upon the shaft I, as shown in the same figure.
